ROLLER-BEARING.

- To all whom it may concern vented certain new and useful Improvements in. Roller-Bearings; and we do declarethe following to be a full, clear, and

exact description of the invention, such as will-enable others skilled in the art to which it'appertains to make and use the same, reference being had to the accompanying drawings, and ,to the letters and figures of reference marked thereon, which form a part of this specification.- a

.This invention relates to new and useful improvements in roller bearings and more particularly to the cage thereof. 7 v

The object of the invention is to provide a roller bearing cage'which is of durable and simple construction and which permits the conical ends of the rollers to enga ethe cones of-the bearings. without interiering with the action of the rollers. Owin constructimi, the rollers and inner unit. Referring to the accompanying drawings, Figure 1 is a side elevation of .our improved Fig. 2 is a section on the line a-a of Fig. 3; Fig. 3 is a section on the line 6-6 of Fig. 1; Fig. 4 is a plan view of one of the retz'iining pockets for the rollers; Fig. 5 is an elevation of the bearing opposite that shown in Fig. 1; and Figs. 6 and 7 of the retaining caring pockets.

Referring more particularly to the drawings; 1 represents the inner and 2 the outer Mounted between said rings 1 and 2 are cylindrical rollers 3 whose diameters are equal throughout their length except at their extreme ends which are tapered. Theinoer ring 1' is adapted to receive a shaft and ring 2 is adapted to be mounted in a journal box. which parts are not shown. To take up the end thrust of the shaft and to prevent the same moving longitudinally in one direction, the rings 1 and 2 are provided with oppositely arranged cone-shaped annular shoulders 4' and 5 which are adapted to be engaged by conical ends Got the rollers. The said rollers act as struts when overcoming the thrust between the two conical shoulders 4 and 5;

Each bearing. consisting of the rings 1 and 2 and the rollers 3, is adapt d to overcome Specification of Letters Patent. Application filed February 17, 1913. Serial no-.-74a,a2a.

To enable the ring 1 and handled as a unit, when placed in a reis adapted fio"overcome the shaft in the opposite. direcrollers 3 being, the bearing is being assembled, for example, the following re-.

tainer means is provided :"7 represents a. cy-' lindrical shell provided with inclined side port-ions8 and side flanges 9 and 10. The said shell 7 .is mounted and 2 adjacent to ring 2. The rollers 3 are mounted between said shell 7 and the ring 1 and said' shell is provided'with openings 11 throughrwhich the rollers S project and which permits said rollersto engage the ring 2. The edges of the openings 11 are preferably chamfered, and the, width of the openings is less than the diameter of the between the rings 1 rollers, so that said rollers are prevented from falling through said openings and out' of the shell. To of: the roller-s3 to engage the conical shoul ders and 5,.the shell 7 and the inclined portions 8 thereof are provided with enlarged openings 12 which lie at the'ends of the openings 11. The outer surfaces of the inclined portions 8 lie below the surfaces of permit the 'conical ends 6 the conical ends 6 of the rollers and the width of the end openings 12 is greater than the diameter of the rollers so as to enable the conical ends 6 of said rollers to project out of the shell and to engage the-conical shoulders 4 and 5. The edges-of the openings 11 the shell 7 while the flanges 9 and 10 prevent the rollers moving longitudinally. The shell 7 .is provided with ears 13 adapted to engage the shoulder 4,-and preventthe shell moving longitudinally relative to the ring 1 in one direction while vents the rollers and opposite direction. The shell 7 therefore maintains the rollers tion on the ringl and permits the rollers 3 and ring 1' to be handled as a unit 7 Having described our invention, we claim p In a bearing of the type specified, the combination with bearing ring provided with'conical shouldersarranged. at opposite ends of said and rollers having conical ends mounted'be tween said rings; of a "cylindrical cage 3 moving I laterally to 3 in their proper posithe shoulder 4 preshell moving in the.

an inner and an outer I rings,

provided with radial openings the under ed es of which are clmmfered to permit the rollers to extend through said radial openings, conical flanges attached to said cylinenlarged ends 01 adrical, cage the conical flanges and the' cage beingp'i'ovided yvith openings which form id radial openings and through which the'eonicul ends of the rollers project, and ears extending -fr0rn one of said conical flangesand engaging the inner bearing ring, whereby said inner bearing ring, said rollers and said cage may be handled as. a unit,- substantially as specified.

In testimony whereof we afiix our signa- 4 tures, in presence of two witnesses.
